air conditioner

["Todd McDonald" <tod47d@xxxxxxxxxxx>]

Greetings again, If that last post didn't cause too much wonky wacky woo-woo, 
here's another. What would the minimum BTU rating would one install in a well 
insulated 22' '67 Safari?  Too big a unit will cycle
on and off frequently as it blasts air to the desired setting and
cycles off, while too small a unit will just run and run-never able to
rest.  I'd like to think that I can get along with the smallest
(7,500? BTU ), but am not sure that would be optimal.  I'm also
interested in the condensate drain install options that have worked in
the pre- factory installed drain era gad-abouts.
